There is a warning marker in my project and once in a while the launch fails because of the following NPE.

java.lang.NullPointerException

Given the impact on the issue, shouldn't we raise this to a P2? / Johan

fix npe

Allow for attribute to be NULL.

Fixed in HEAD, now checks to see if the severity attribute is NULL. MIkhail, does this look right to you?

Ken, it seems to be caused by a race condition which is very difficult to catch - when I set breakpoints it works fine. 
I don't think it is worth to try to fix it "properly", so this solution is acceptable.
